+
+QuestPDF is an open-source .NET library for PDF documents generation.
+
+It offers a layout engine designed with a full paging support in mind. The document consists of many simple elements (e.g. border, background, image, text, padding, table, grid etc.) that are composed together to create more complex structures. This way, as a developer, you can understand the behavior of every element and use them with full confidence. Additionally, the document and all its elements support paging functionality. For example, an element can be moved to the next page (if there is not enough space) or even be split between pages like table's rows.

-2022.8.0:
-
-- Improved library performance,
-- Breaking change: changed default font from Calibri to an open-source Lato,
-- Default font files are included with the nuget package, making it safe to deploy on any environment,
-- Default font files are significantly smaller, so output document files should be smaller too (up to 20x reduction in size),
-- When requested font is not available on the runtime environment, library provides list of available fonts,
-- Fixed a rare layout overflow exception with the Inlined element,
-- Fixed a memory leak connected to the HarfBuzz library.
-
-
-2022.8.1:
-- Fixed: default text style does not always work
-- Fixed: page breaking rendering does not work in very specific corner cases
-- Stability improvements for text wrapping
-- Updated stability of rendering elements in negative space
-- Optimization for the Column element: do not measure child when available height is negative
-
-2022.8.2
-- Fixed: the Column element incorrectly renders zero-height elements.
+Feature: implemented LetterSpacing property for the Text element
+Improvement: the Text element API accepts now only string values, objects are not automatically converted anymore
+Fix: the Alignment element incorrectly limits size of its child when only one axis is set (horizontal or vertical)
+Maintenance: Updated SkiaSharp dependency to 2.88.3
